Manual: Liquipedia Help

The extension can be loaded in Lua modules by the Scribunto extension like this:

VariablesLua=mw.ext.VariablesLua

Functions are based on the ones provided by the Variables extension, adding some more utility.

VariablesLua.vardefine( name, value )

Stores the given value under the given name. An empty string is stored if the value is nil.

VariablesLua.vardefineecho( name, value )

Identical to VariablesLua.vardefine, but returns the value after storing it.

VariablesLua.var( name, default )

Retrieve a variable stored under the given name.

VariablesLua.varexists( name )

Check if a variable exists. Returns a boolean value.

VariablesLua.var_final( name, default )

Returns the last value stored (i.e. the last VariablesLua.vardefine or #vardefine in the code). The value can only be returned and not used in the Lua code.
